If you are looking for the best bang for your buck in quality. I think the Sheraton residences pudong is a great deal. I have gotten rooms there (I live in Shanghai, needed one night for spg plat) for $85. The rooms were nicer than westin and got a suite upgrade as spg gold. The downside is there is nothing to do around the hotel. But only a 10 minute taxi to the bund.

Also you could do taxi and maglev in 25 minutes to pudong airport.
